Avalanche Summary
A few small natural and rider-triggered wind slab avalanches up to size 1.5 were reported on Thursday and Friday. These were from steep East-facing slopes immediately lee of ridges.
Snowpack Summary
Up to 20 cm of dry snow sits on a variety of old surfaces including a melt-freeze crust on solar aspects in the alpine, smooth old snow on higher elevation lee slopes, and well-developed surface hoar in sheltered areas at treeline and lower elevations. This dry surface snow is capped by a sun crust on steep solar aspects or a fresh layer of surface hoar on sheltered and shady slopes. Variable winds have created soft wind slabs in lee and cross-loaded terrain in alpine areas. The mid and lower snowpack is generally strong.
